LENS-SETTING FOR STEREOSCOPES.

SPECIFICATION forming part of Letters Patent No. 748,676, dated January 5, 1904.

' Application filed April 30, 1903- Serial No. 154,927. (No model.)

' To all whom it may concern:

- fication.

The invention relates to improved means for fastening the ordinary lenses of stereoscopes in the lens frame or holder.

The object of the invention is to provide simple and effective means for confining the lenses within their respective sockets or seatings in the lens-frame without the aid of wedges, pins, screws, putty, metal spurs, or indentations in the walls of the sockets, as is now commonly done, which is accomplished by the employment of a set of metallic socketlinings and lens-caps, by the aid of which any lens may be accurately fixed in its socket and securely fastened therein by simply folding down flexible flanged edges of the lens-caps,

as will hereinafter more clearly appear.

The invention is fuliy illustrated in the drawings, wh'erein Figures 1 and 2 show two opposing socketlinings. Fig. 3 shows the same parts in their adjunctive relation. Figs. 4: and 5 show views of the two opposed lens-caps. Fig. 6 exhibits in perspective said four parts assembled in their proper positions as detached from the lens-frame. Fig. 7 is a view of an ordinary stereoscopic lens. Fig. 8 is a perspective view of the invention as applied to a lens-frame.

In this case I have shown an ordinary wood frame, through which are made two rectangular plain orifices or sockets. Both sides of this frame are alike comparatively; Two socket-linings B and C, which are counterparts of each other, are provided, which may be struck up from sheet metal, each of which has two opposite leaves f f and h h struck out from the center of each blank and folded down at right angles, as shown. These leaves form the wall-linings of the lens-socket when inserted in place in the frame, the leaves bearing against the sides of the opening and the flanges g and i resting flat against the sides of the frame. One lens-cap, D, has its central face cut away, as shown,,leaving a narrow rim 0, against the under side of which the lens bears when in position. The walls jj just flt inside the square inclosure seen in Fig. 3, so that the flanges 10 is will bear upon the under side of the flanges 1' 7 as seen in Fig. 6. The parts B, O, and D can bemade complete in advance,-as shown, and can be assembled without bending any part of either. After putting these three parts togetherin the frame the lens L is put in position, with one side resting against flange 0. Then cap E is put in position by passing the leaves Z Z through between leaves f f and the edges of the lens, so that the flange-rim n will bear against the face of the lens and the flanges m m will protrude above the face of flange g. The caps are then firmly pressed against the lens, and the flanges m m are folded down, as I seen in Fig.6.

It will be seen that the lens is practically held in position by the caps alone. The socket-linings do not act as binders to hold the lens in position; but they serve other uses in the combination, inasmuch as they furnish a metallic flange around each socket, which adds to the finish of the frame and also furnishes a sharp corner over which to fold the flanges m m of the lens-cap. Besides, this metallic lining for the walls of each socket protects the wood of which they are made and afiords better protection for all the parts.

the upstanding leaf for final insertion in place to close the assemblage; but all the other parts may be made complete beforehand, so.

that in practice to set a lens the parts B- and O are each put in place by forcing the leaves of each into the socket from opposite sides of the frame, with leaves disposed at right angles with each other, until the flanges bear firmly against the faces of the frame. Then one of the caps is put in position and the lens dropped into position, after which the leaves of the other cap are passedthrough the open slits left between the edges of the lens and the walls of the socket-linings and the flange is pressed firmly down upon the face of the lens. Being so held, the edges of the leaves which project above the face of the flange of the socket-lining are then folded down and the setting becomes complete.

I therefore claim as my invention, and desire to secure by Letters Paten t,the following:

1. A look for confining a lens in its socket consisting of two binding-caps, each comprising a facial rim which covers the edge of one side of the lens, two opposite leaves which embrace two opposite edges of the lens and overfolded flanges atthe ends of the leaves, the leaves of the two members being arranged at right angles to each other, substantially as specified.

2. A socket-lining fora lens-cavity in a lens-frame of a stereoscope, consisting of two similar members each of which consists of a flange-rim which surrounds the cavity and bears against the surface of the frame and two opposing leaves bent to fit the two opposite sides of the socket, the two members being combined so that the leaves of one member will be disposed transversely to the leaves 3f the other member, substantially as speci- 3. The combination with a lens-frame of the two described tran sversely-disposed lenscaps having leaves, rims and flanges arranged and adapted to hold a lens in position substantially as specified.

4. The combination with a lens-frame of the two similar socket-linings having leaves and flanges arranged and adapted to form an internal lining for a lens-socket, and means for holding said linings in position substantially as specified.

5. The combination in a stereoscopic lensframe of the socket-linings and transverselydisposed lens-caps, said linings and caps being provided with retaining-flanges substantially as specified.

6. The combination with a lens-frame havin}; one or more rectangular lens-cavities, of a socket lining consisting of two similar members each of which consists of a facefiange rim which surrounds the socket and rests upon the surface of the frame and two opposing leaves bent to fit the two opposite sidespf the socket, the two members being combined so that the leaves of one member will be disposed transversely to the leaves of the other member, and means connected with such members for confining them in place, substantially as described.

In testimony whereof I have hereto subscribed my name, this 28th day of April, 1903, in the presence of two witnesses.
